A uniform ladder of mass m and length L leans at an angle θ against a frictionless wall. If the coefficient of static friction between the ladder and the ground is 0.43, what is the minimum angle at which the ladder will not slip?

Do i use the equation
Fn- Mg= 0

yes, you start with that. I would sum moments about any point and those moments to zero. And finally, the sum of forces in the horizontal are zero also.
